A woman was very distraught at the fact that she had not had a date in quite sometime. Afraid she might have something wrong with her she decided to employ the medical expertise of a sex therapist. 

Her personal physician recommended Dr. Wang, a well-known Chinese sex therapist. So she went and saw him. Upon entering the examination room, Dr. Wang took one look at her and said, "okay, take off aw your crows." 

She quickly disrobed and stood naked before him.

"Now, " said Wang, "get dow on knees and craw reery, reery, fass away from me to the other side of room."

Having done that Dr. Wang said, "okay, now turn around and craw reery, reery fass to me." Once again she obliged.

Dr. Wang slowly shook his head, "okay, your probrem vaywe, vaywe bad, you have Ed Zachary Disease.....worse case I ever see....that why you not have dates."

Confused, the woman asked, "What is Ed Zachary Disease?" 

Wang replied, "It when your face rook Ed Zachary rike your ass."
